Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed February 8, 1905. Serial No. 300,138.

To all whom it may concern.-

Be it known that I, JOHN W. MCDOWELL, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in a Combined Water-Bag, Syringe, andColonic Irrigator, of which the following is a specification.

This invention relates to an improved water bag, fountain syringe, andcolonic irrigator, the irrigator being of the type in which the ressurefor injecting the liquid is iuriished by the weight of the patients Inall prior devices of this type, so far as I am aware, great difficultyhas been ex erienced in providing a re ulating-valve which will preventleakage tfhrough the moving parts when the irri ator is in use. Thisdiiliculty is obviate by the construction shown in the drawingsaccompanying this specification, in which Figure 1 is a plan view of mydevice arranged as an irrigator. Fig. 2 is a longitudinal sectionshowing a tube attachment for use as a fountain-syringe. Fig. 3 is anenlarged section of the base of the irrigatornozzle. Fi 4 is a sectionshowing the application o the closingcap. Fig. 5 is an elevation of thedevice arranged as a fountain-syringe, and Figs. 6 to 9 are detail viewshereinafter referred to.

1 is the rubber receptacle provided with side and end orifices 2, whichwhen not re quired for use may be closed with caps 2, preferably madeinterchangeable.

3 3 are valved attachments, the former bein arranged to receive asuitable length of flexible tubin 4 and the latter to receive a nozzle5, whic 1 nozzle may also be attached, as shown in Fig. 5.

6 6 are screw-plugs each larger in diameter than the orifice 2 which itis adapted to cross to practically close said orifice, as clearly shownin Fig. 9, the ends of said: lugs being preferably coneaved and pro 'dedwith disks or short cylinders 7, of rubbei or the like, sufiicientlyflexible and resilient, especially at their forward or free ends, to bepartially straightened, and thus expanded, 1

y hydraulic pressure acting on their free faces. The forward portion ofthe bore which receives the plugs 6 6 is without interior screw-threads,and the resilient pieces 7 are preferably of sufficient length to spanthe orifices 2 when moved thereover and seal them when the be is beingfilled, &c'..

In order that the dis 5 may be attached to the tips of the plugs andrenewed if necessary, the valve-casings are located orifices 10, sightly larger than the threaded orifices through which the plugs pass,and the orifices 10 are also provided with rubber-lined caps 2". Thejunction of the smooth and threaded portions of the interior of thevalvc-iittin s opposite the caps 2 forms a coned seat, as est shown inFig. 9.

The 0 eration of the device as a hotrwater bag wil be clearly ap arent.All fittings are removed, and hot i orifices 2, one of which may serveas a filling-orifice, are closed with the caps 2. Its operation as afountainsyringe will be apparent from Fig. 5. When used as a colonicirrigator, the fittings are arran ed as shown in Fig. 1, the filled bagplacer on a seat of convenient height, the fluted nozzle iven a rectalinsertion, and the patient seats iimsclf upon the reservoir with thevalve-plug directed toward the front of the body. The flow of the fluidis then readily regulated either by manipulation of the valve or b varing the wei 'ht upon the reservoir. W 1611 the valve is iiilly opened,as shown in Fig. 9, it will be readily understood that the greater thefluid-pressure upon the yielding disk 7 the more secure the sealing ofthe valve against leakage. The same is true of the valve 6 when thedevice is used as a fountain-syringe.

What I claim is I 1. In a combined water-bag, syringe and irri ator, acompressible receptacle provided with a plurality of orifices eachhaving a removable valve structure, and a sealing-cap interchangeablewith said valve structures for closing either of said orifices;substantially as described.

2. In a device of the class described, a regulating-valve comprising acasing having a straight orifice therethro u h, and a closingplug ofgreater diameter than the straight orifice and movable in a transversepassage provided with suitably- ICO across said orifice, said plughaving a resilient tip constructed and arran ed to seat a ainst that endof the passage t l hrough whic the plug moves, to seal said transversepassa e against leakage when the valve is fully opened; substantially asdescribed.

3. In a device of the class described, a valve structure comprising acasing having no two straight, intersecting orifices of different fconed seat adjacent to the screw-threaded diameters therethrou h, ascrew-plug movable longitudinally 0 the larger orifice and transverselyof the smaller orifice, to close the latter, said plug having aresilient memher at its inner end arranged to contact with a seat atthat end of the orifice at which the plug enters to seal the largerorifice against eakage when the valve is fully opened; substantially asdescribed.

4. In a device of the class described, a valve comprising a casin havinga straight outlet-orifice therethroug and a transverse passa e largerthan the outlet-orifice, screwthreaded for a portion of its length andintersecting said orifice, said passage having a portion, ascrew-threaded plug fitting the threads of said transverse passage andmovable across said outlet-orifice to close the 2o same, said plughaving a resilient member secured to its inner extremity and adapted tocontact with said coned seat to prevent leakage around the screwplugwhen the valve is in open position; substantially as 25 described.

In testimony whereof I aflix my signature in presence of two witnesses.
